Embodiment 1

[0023] The present embodiment provides a method for regulating and controlling the flowering period of Spiraea, comprising the steps of:

[0024] S1, plant spirea in the greenhouse, apply potassium dihydrogen phosphate in May every year, and apply 5kg per mu; promote the early maturation of spirea plants;

[0025] S2. Control the water content of the soil in the greenhouse to 75% in October every year to promote a large amount of abscisic acid in the Spiraea plant; seal the greenhouse after the water control is over;

[0026] S3, spray 30wt% ethephon solution and 2wt% abscisic acid solution to Spiraea foliage, spray to the foliage drip, the volume ratio of ethephon solution and abscisic acid solution is 2:1; stuffy shed for 7 days ; 95% of spiraea leaves fall off;

[0027] S4, open the shed for ventilation, pour water thoroughly after 1 day, spray 0.05% gibberellin solution, and the spraying rate is 20L / mu;

[0028] S5. Keep the temperature in the shed at 18° C., bloom after...

Embodiment 2

[0030] The present embodiment provides a method for regulating and controlling the flowering period of Spiraea, comprising the steps of:

[0031] S1, plant spirea in the greenhouse, apply dipotassium hydrogen phosphate in July every year, and apply 10kg per mu; promote the early maturation of spirea plants;

[0032] S2. Control the water content of the soil in the greenhouse to 55% in September every year to promote a large amount of abscisic acid in the Spiraea plant; seal the greenhouse after the water control is over;

[0033] S3, spray 60wt% ethephon solution and 1wt% abscisic acid solution to Spiraea foliage, spray to the foliage drip, the volume ratio of ethephon solution and abscisic acid solution is 2:1; stuffy shed 10 days ; 98% of spiraea leaves fall off;

[0034] S4, open the shed for ventilation, pour water thoroughly after 2 days, spray 0.01% gibberellin solution, and the spraying rate is 10L / mu;

[0035] S5. Keep the temperature in the shed at 26° C., bloom aft...

Embodiment 3

[0037] The present embodiment provides a method for regulating and controlling the flowering period of Spiraea, comprising the steps of:

[0038] S1, plant spirea in the greenhouse, apply dipotassium hydrogen phosphate in June every year, and apply 8kg per mu; promote the early maturation of spirea plants;

[0039] S2. Control the water content of the soil in the greenhouse to 60% in September every year to promote a large amount of abscisic acid in the Spiraea plant; seal the greenhouse after the water control is over;

[0040] S3, spray 35wt% ethephon solution and 3wt% abscisic acid solution to Spiraea foliage, spray to the foliage drip, the volume ratio of ethephon solution and abscisic acid solution is 4:1; stuffy shed 9 days ; 98% of spiraea leaves fall off;

[0041] S4, open the shed for ventilation, pour water thoroughly after 2 days, spray 0.02% gibberellin solution, and the spraying rate is 15L / mu;

[0042] S5. Keep the temperature in the shed at 20° C., bloom after...

Abstract

The invention relates to a spiraea florescence control method, and belongs to the technical field of agriculture. The method comprises the following steps that S1) spiraea is planted in a greenhouse,and fertilized with phosphorus potassium from May to July each year in the amount of 5 to 10 kg per mu; S2) from September to October each year, the water content of soil in the greenhouse is controlled within 55-75%, and the greenhouse is sealed after water control; S3) leaves of the spiraea is sprayed with an ethephon solution and an abscisic acid solution till liquid is dropped from the leaves,and the greenhouse is closed for 7 to 10 days; S4) the greenhouse is opened for ventilation, through watering is carried out 1-2 days later, and a gibberellin solution is sprayed in the amount of 10-20L / mu; and S5) the temperature in the greenhouse is kept between 18 and 26 DEG C, and flowering is realized after 50-70 days. Thus, the spiraea can be flowered in advance, the florescence is prolonged, the quality and ornamental value of the spiraea are both improved, and the labor intensity is reduced.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for regulating the flowering period of spirea. Background technique [0002] Spiraea salicifolia (Spiraea salicifolia L.), also known as horse urine show, leech grass, leech tip, etc., is an upright shrub of Rosaceae and Rosaceae, up to 2 meters. Young shoots are pilose and fall off when old; winter buds have several brown exposed scales, sparsely pubescent leaves are oblong-lanceolate or lanceolate, leaves are oblong-lanceolate to lanceolate, inflorescences are oblong or pyramid-shaped Inflorescence panicles, pink petals, flowering period June-August, fruiting period August-September. Spiraea is distributed in East Asia and southeastern Europe. [0003] Spiraea has been widely used as fresh-cut flowers due to its many advantages such as beautiful flower shape and elegant flower color, and has been artificially produced on a large scale. Spiraea is aff...
